    u(t) is called 60 times per second.
    t: Elapsed time in seconds.
    S: Shorthand for Math.sin.
    C: Shorthand for Math.cos.
    T: Shorthand for Math.tan.
    R: Function that generates rgba-strings, usage ex.: R(255, 255, 255, 0.5)
    c: A 1920x1080 canvas.
    x: A 2D context for that canvas.

u/BuRRak

Nice! Looks quite similar to my dweet, d/7996 :D
u/iverjo

You just taught me that c.width=-1; actually sets the canvas width to 300. Clever!
u/BuRRak

300 is the default size of a canvas so giving a negative number will just reset it to defaults i guess
u/prplz

iverjo: I give credit to u/jylikangas for the -1 width trick
u/prplz

BuRRak: Thanks, same goal different approach :)
